Enableing PME on Win7 Network Cards for WoL - Group Policy?

I recently discovered that the reason our Optiplex 780's were not waking on LAN was because Windows Power Event (PME) was set to "disabled" under Network Adapters > properties > advanced.

Now I'm asking: is there a way to set the network adapter's "PME" setting to enabled via group policy? Is there a registry entry?

Thanks

There is a Dell utility available that will change the bios setting from within windows. Also check out poweronmypc.com it's a nice Internet based wake on lan tool.

We have about 120 computers on the network. When we build a box we fix the bios and enable WoL and disable low power mode.
However, with the new Opti 780's, you also need to go into device manager > network adapter > properties > advanced and enable PME in order for WoL to work. My question is, is this network adaptor setting available in the registry to be pushed out through group policy.

A third party application is not an option for us as we have a large network and try and shy away from loading them up with apps and software to do things we could just push out through policy.

If you are a regular Dell customer and are oredering BTO machines I believe there is a way to get them to set the BIOS the way you want it during the system build. Which would eliminate this whole issue Talk to your rep.

I do ot believe that setting is available in the registry because it modifies a hardware bit.

the poweronmypc.com is not an appliaction, there is nothing to install on the workstatons, only 1 small TSR on a server for the whole network which is why I thought it was a fit for you.

Any more input on whether the network cards in 780's and their 'PME' setting can be set to enabled/disabled through the registry?
*note* above is the entirety of my question. My question is not about BIOS, low power state, WoL enabled being enabled or disabled, or any 3rd party app options. My question is regarding the registry and whether the PME option of a network card can be set to "enabled" in the registry or not.

poweronmypc isn't something we're interested in and we have no problem changing the bios ourselves because we order so few computers at a time. Thanks though ts4673.

I believe I already answered your question. Dell bios cannot be changed through the registry and the hardware properties of the lan card also can't be changed in the registry. The power management settings for the worksation in general can be set through the registry.

Hardware properties of the lan card can be changed through the registry.
Finally found the setting under:
Local_machine > System > Controlset001 > Control > Class > {4D36E972-E325-11CE-BFC1-08002bE10318} > 0008 (or 0007 depending on your OS and build) > then key "EnablePME". "1" is enable, "0" is disable.
Found a direct correlation between this and the NIC card: checking under advanced adapter settings and seeing PME disabled, I went into that registry key and set "EnablePME" to "1" which set the adaptor settings directly.
This can be pushed through group policy, so I guess I answered my own question.
 
All I need now is someone to help me hammer out the differences between the registry and advanced NIC settings on different computers. That way we know, "Push this policy for XP computers, and this for Win7" or "This for Optiplex 780's, this for 760's" I.E.
Why "EnablePME" sometimes is in folder 0008 and other times is in folder 0007 in the registry (is it just the difference in OS?).
Why, under advanced adaptor settings for the NIC, PME isn't even an option most of the time: (It's not listed under 'advanced' for driver version 10.3.39.0, IS listed for driver ver. 10.5.1.0, but then isn't listed again for the newest driver 11.5.4.0. Is there an option during installing the driver that allows for more options once installed? Like a basic and advanced install options or something?

PME is power management enable. There is a registry entry for it but I do not believe it is settable as a group policy for a windows xp machine. Hence the answer is still no. You may also to need to enable wake on magic packet if not enabled by default which there is no key for as it is a hardware setting.
